Giampiero Trupia has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 5220217
    Abstract: The circuit comprises a first switching circuit which receives at an input a system clock normally provided for the operation of the integrated circuit and produces at an output a machine clock normally coincident with the system clock, circuitry for clamping the first switching circuit responsive to a firing signal of the serial operational analysis device determines which state the machine clock is clamped in and second switching circuit which receives at an input the system clock and is responsive to the firing signal to produce a scanning clock which repeats the system clock in an inverted or non-inverted manner according to the state in which the machine clock has been clamped.
    Type: Grant
    Filed: December 18, 1991
    Date of Patent: June 15, 1993
    Assignee: SGS-Thomson Microelectronics s.r.l.
    Inventors: Flavio Scarra, Maurizio Gaibotti, Giampiero Trupia
